Diastereoselective Reduction of α-Imino Esters with Tris(trimethylsilyl)aluminum
摘要:
Tris(trimethylsilyl)aluminum was found to be a good chemoselective reducing reagent for alpha-imino esters to give alpha-amino esters in good yields. Application to the reduction of 3,5-disubstituted 5,6-dihyro-2H-1,4-oxazine2-ones realized a stereoselective conversion into cis-3,5-disubstituted morpholine-2-ones.
